In Songkeng Village, Hanggai Town, Anji County, there is a mountain rush called 'Longtouwu', and the hill of 'Longtouwu' is called 'Zhanlonggang'. There is also a long trench on Zhanlonggang. People say that during the Hongwu period, Zhu Yuanzhang's military advisor Liu Bowen was ordered to go to various places to cut off dragon veins. Liu Bowen passed by "Longtouwu" and found a dragon vein on the hill, so he hurried up the mountain to cut off the dragon vein. Liu Bowen could not cut off the dragon vein on the hill and just left They dug a long ditch (the ditch is still there). When Liu Bowen took a closer look, he found that the dragon was no longer there, so Liu Bowen had to go down the mountain and return to Beijing. It turns out that when Liu Bowen went up the mountain to kill the dragon, he did not worship the local "Dongdi Temple" (this temple is still there) and "Tudi Temple". The two temple gods were very dissatisfied with this matter, so they rescued a red dragon from "Longtouwu" and released it. There is a deep pool in the mountain called "Yekengwu" on the opposite side. Later, the locals named the pool "Longtan". Besides, after the red dragon was rescued, in order to thank the two temple gods for making the local area have good weather every year, the local people built a "Dragon King Temple" not far from the "Longtan" in order to thank the red dragon (this temple is still there now). There is also a dragon dance in the first lunar month. The custom of dragon dancing in the first month has been passed down to this day.
